The FLUX 3 Max API is a pay-per-second way to call the FLUX 3 Max video model from your own code, sold by API providers: fal, where the model launched, plus apimodels.app and Krea. Flux3Max, this site, is a web app and has no API. Use an API to build FLUX 3 Max into your own product or pipeline; use the web app if you just want to make videos.
Updated October 21, 2026. Prices and endpoints as each provider lists them; Flux3Max is not affiliated with any of them.
Price per second of generated video.

Yes. fal, where FLUX 3 Max launched, sells it as an API, and so do apimodels.app and Krea. Each bills per second of generated video and takes a prompt plus an optional first frame, last frame or keyframes.
On fal it lists at $0.17 per second at 720p and $0.29 at 1080p, discounted to $0.0425 and $0.0725 until November 7, 2026. apimodels.app lists $0.221 and $0.377, with $0.085 and $0.145 until the same date; Krea lists $0.17 and $0.29. A 10-second 720p clip at fal’s list price is $1.70.
Not that we can find. Black Forest Labs’ own API lists FLUX 3 video, the base model, but not FLUX 3 Max, which fal Research post-trained from it. Use one of the providers on this page for FLUX 3 Max.
No. Flux3Max is a web app for making FLUX 3 Max videos in the browser, with Google sign-in and credits. For programmatic access, use one of the providers above.
fal says content generated through its API can be used in commercial projects and points to its terms for the details. Check the terms of whichever provider you use.
Figures from model makers are their own measurements unless stated.
